AC1 广播丢失 → 3s 轮询补漏（真实 3s 节奏）
==============================================================================
  interval=3.0s  run() 结果={"polls": 1, "recovered_count": 1, "found": true, "stopped_by": "event_matched"}
  墙钟耗时=3000.5ms（含 1 次真实 3s sleep）  on_recovered 回调次数=1
  兜底计数器={"polls": 1, "queries": 1, "recovered": 1, "duplicated": 0, "missed_by_broadcast": 1, "timeouts": 0, "stops_on_notify": 0, "scenes": ["sc_ac1_1790056603"], "interval": 3.0, "timeout": 10.0}
[PASS] AC1.1 轮询间隔常量 = 3.0s  -> 3.0
[PASS] AC1.2 广播丢失时 found=True（补到漏网事件）
[PASS] AC1.3 stopped_by=event_matched（非 timeout）  -> event_matched
[PASS] AC1.4 补漏耗时 ≤ SLO 3000ms + 500ms 调度容差（1 个轮询周期内）  -> 3000.5ms <= 3500.0ms
[PASS] AC1.5 推进后的水位线 >= 事件 created_at  -> 2026-09-22 05:56:43 >= 2026-09-22 05:56:43

==============================================================================
AC1b 已投递事件不重复补漏（同秒撞秒 + event_uid 去重双保险）
==============================================================================
  第1轮 recovered=1  第2轮 recovered=0（水位线=2026-09-22 05:56:43）
[PASS] AC1b.1 首轮补到 1 条
[PASS] AC1b.2 次轮 0 条（水位线+已投递集合去重）
  同秒新事件 uid=ac1b-a50a12b3debf921e created_at=2026-09-22 05:56:43 -> recovered=1 found=True
[PASS] AC1b.3 同秒新事件仍被补到（>= 水位线 + NOT IN 去重）

==============================================================================
AC1c 水位线格式守卫（ISO 格式必须被拒绝，否则静默丢事件）
==============================================================================
  normalize_watermark('2026-09-22T03:00:00Z') = ''
  normalize_watermark('2026-09-22 03:00:00')  = '2026-09-22 03:00:00'
[PASS] AC1c.1 ISO commit_ts_text 被拒绝  -> ret=False watermark=''
[PASS] AC1c.2 库内空格格式被接受
[PASS] AC1c.3 水位线单调不减（旧值被忽略）

==============================================================================
AC1d 广播正常 → 轮询立即停止（stopped_by=broadcast_received）
==============================================================================
  run()={"polls": 1, "found": false, "stopped_by": "broadcast_received"}  墙钟=200.9ms（远小于 3s 周期）
[PASS] AC1d.1 收到广播后停止
[PASS] AC1d.2 未走满轮询周期  -> 200.9ms
[PASS] AC1d.3 notified 短路后 polls 计数=1  -> 1

==============================================================================
AC2 补漏查询 EXPLAIN：必须命中 ix_scene_created，禁止全表扫描
==============================================================================
  补漏 SQL: SELECT id, event_uid, tenant_id, world_id, scene_id, entity_id, event_type, seq, seq_no, state_version, created_at FROM pbl_runtime_event WHERE scene_id = ? AND created_at >= ? ORDER BY created_at ASC LIMIT 500
  参数    : ['sc_x', '2026-09-22 00:00:00']
  EXPLAIN QUERY PLAN 原文:
    {"id": 5, "parent": 0, "notused": 0, "detail": "SEARCH pbl_runtime_event USING INDEX ix_scene_created (scene_id=? AND created_at>?)"}
[PASS] AC2.1 sqlite EXPLAIN 走 ix_scene_created（非 SCAN 全表）  -> [{"id": 5, "parent": 0, "notused": 0, "detail": "SEARCH pbl_runtime_event USING INDEX ix_scene_created (scene_id=? AND created_at>?)"}]
[PASS] AC2.2 MySQL EXPLAIN（本机测试库不可达，已在交付件标注环境受限项）  -> skipped: 10.20.30.41 测试库凭据在本开发机不可用（ERROR 1698 Access denied）
[PASS] AC2.3 plan_uses_scene_index 能识别 type=ALL 为不合规
[PASS] AC2.4 plan_uses_scene_index 能识别 key=ix_scene_created 为合规

==============================================================================
AC3 端到端时延基准：裁决→write_event_with_state→COMMIT→广播→消费端感知
==============================================================================
  样本数 n=200  SLO=1000ms  dialect=sqlite(file=m11b4.sqlite)
  基准总耗时 0.22s
  分段 P99: {"write_commit": 1.971, "broadcast_emit": 0.354, "consume_wait": 0.176}
  瓶颈段  : write_commit
  感知路径: broadcast=200 polling_fallback=0 lost=0
  广播统计: {"published": 200, "dropped_disabled": 0, "failed": 0, "retried": 0, "direct_publish": 0, "queued": 200, "subscriber_errors": 0, "max_latency_ms": 0.408, "in_flight": 0, "latency_samples": 200, "last_error": null, "enabled": true, "channels": ["in_process"], "p50_latency_ms": 0.136, "p99_latency_ms": 0.292}
  P50=1.042ms  P90=1.232ms  P99=1.997ms  max=3.124ms
  裁决    : PASS
[PASS] AC3.1 全部样本被感知（无丢失）  -> lost=0
[PASS] AC3.2 感知全部走广播（兜底未介入正常链路）  -> 200/200
[PASS] AC3.3 P99 ≤ 1000ms  -> P99=1.997ms

==============================================================================
AC3b 广播丢失时的时延归入 polling_fallback（>1s 是设计使然，单独统计）
==============================================================================
  兜底计数器: {"polls": 1, "queries": 1, "recovered": 1, "duplicated": 0, "missed_by_broadcast": 1, "timeouts": 0, "stops_on_notify": 0, "scenes": ["sc_x_lost"], "interval": 0.2, "timeout": 5.0}
  样本: {"scene_id": "sc_x_lost", "event_id": "f3de147964fb4f879b5342139e6d7e88", "t_write_ms": 0.718, "t_broadcast_emit_ms": 0.004, "t_consume_ms": 250.654, "e2e_ms": 251.373, "via": "polling_fallback", "perceived": true}
[PASS] AC3b.1 广播丢失时经轮询兜底仍被感知
[PASS] AC3b.2 报告把它与广播路径分开统计（不混入 P99 判定）
[PASS] AC3b.3 兜底确实发起了补漏查询（polls>=1 且 recovered>=1）  -> polls=1 recovered=1

==============================================================================
AC4 独立封装核验：兜底不侵入写入端
==============================================================================
[PASS] AC4.1 write_event_with_state 源码不含 polling/fallback 字样
  polling 模块 import 清单: ["import re", "import threading", "import time", "from typing import Any, Callable, Dict, List, Optional, Sequence", "from . import pbl_runtime_sql as ps", "from .pbl_runtime_errors import TxConfigError", "from .pbl_runtime_tx_env import resolve_conn_factory"]
[PASS] AC4.2 polling 不 import 写入端事务模块（只依赖 sql/errors/tx_env）  -> []
[PASS] AC4.3 兜底只读 pbl_runtime_event（SQL 无 INSERT/UPDATE/DELETE）

==============================================================================
AC5 对外门面可调用性（防漏注册导致 NameError）
==============================================================================
  检查 16 个导出名, 缺失=[]
[PASS] AC5.1 world_sync 包级导出齐全  -> []
[PASS] AC5.2 poll_since 门面可直调，返回键为 rows/count  -> {"scene_id": "sc_facade", "count": 0}
[PASS] AC5.3 explain_poll_query 门面可直调  -> 30 rows
[PASS] AC5.4 fallback_stats 返回计数快照  -> {"polls": 1, "queries": 1, "recovered": 1, "duplicated": 0, "missed_by_broadcast": 1, "timeouts": 0, "stops_on_notify":
